Definitions

  • This invention relates to apparatus and method for contacting liquids and gases, comprising a contacting chamber enclosed by a tubular wall through which the gas and liquid move concurrently in an upward or downward direction, the said chamber having gas and liquid inlets at one end and gas and liquid outlets at the other.
  • Several contacting units of such construction can be combined, e.g., arranged in parallel or may be arranged in series to effect over-all countercurrent flow between the liquid and gas.
  • gas is herein used generically to include vapor.
  • the liquid is entrained in the form of small droplets-which can be made smaller by using atomizer means at the said inlet opening(s) and connecting the atomizer means to a liquid supply duct.
  • atomizer means at the said inlet opening(s) and connecting the atomizer means to a liquid supply duct.
  • a large surface of the liquid is exposed to the gas, which is very desirable for promoting the mass transfer between the gaseous and liquid phases.
  • the two phases are separated, and particularly in the application of this ty e of contacting to fractional distillation, it is of great importance that this separation occur at as short a distance after effective contact and mass transfer as possible.
  • the separation of the liquid droplets from the gas is effected by the same rotary motion of the gas as that by which the droplets were produced. This motion fiings the liquid droplets to the wall of the cylindrical chamber, and the layer of liquid thus formed on the wall flows outward through holes or slits in the said wall to a collecting chamber; the gas escapes through the upper, open end of the cylinder.
  • the separation of liquid droplets from the gas can be improved by installing a second vane deck just before the end of the cylinder, with a view to boosting the rotary motion of the gas, which decreases as a result of friction.
  • the droplets therefore, originate within the rotating gas stream, so that at that moment the mass transfer begins.
  • inertial forces become active and the gasliquid separation become effective, so that the liquid droplets are coalesced and their surface area reduced; hence the efiiciency of the overall mass transfer is limited.
  • Application of second vane deck to improve the separation efficiency does not of itself destroy the inertial separating forces of the first deck while, moreover, there follows the unattractive result of a greatly increased pressure drop per unit clue to the flow of the gas therein through two vane decks.
  • the foregoing objects are attained by providing the chamber wall over most and, preferably, all of the section of its length wherein mass transfer is to occur, with special elements which create turbulence and cause liquid which has collected on the wall to be reentrained.
  • a device for separating the liquid droplets from the gas which is usually, although not necessarily, of the inertial type.
  • the contactor comprises a tubular wall, e.g., a vertical cylinder, having means at the supply end, e.g., the bottom, for admitting a stream of gas and introducing the liquid thereinto, inertial means for separating the entrained liquid from the gas stream and separately discharging the separated gas and liquid at the other end, and, intermediate said supply end and the separator, projections on the inside of the tubular wall which are arranged to facilitate the entrainment and re-entrainrnent of the liquid in the gas stream.
  • a tubular wall e.g., a vertical cylinder
  • the said tubular wall may have a constant, circular cross section, but the invention is not limited to either of these features.
  • a polygonal cross section may be used, and the cross sectional area and/ or outline may be variable at different levels.
  • the projections may be flat strips that extend from the tubular wall for suitable distances, preferably between 1 and 20% of the smallest diameter of the contacting chamber enclosed by the tubular wall. According to a preferred embodiment these strips are arranged as a grid, to form an annular structure having the appearance of an egg crate when viewed radially. For constructional reasons it is advantageous to place the strips perpendicular to the wall.
  • the choice of radial extent of the projections will depend upon the thickness of liquid film of layer which collects on the column wall, a greater radial dimension being used as the layer is thicker.
  • the gas stream is normally admitted axially into the supply end of the contacting chamber refined by the tubular wall and the liquid is fed into this stream at the same end in any suitable manner to effect entrainment by the gas.
  • atomizers for producing small droplets due to the action of the aforesaid projections, although the invention is not restricted to the avoidance of atomizers.
  • the liquid can be supplied to the tubular wall through one or a series of holes spaced equally about the circumference at the supply end swept off or along said wall by the gas stream. The part of the liquid swept along the wall is entrained as droplets by the action of the projections.
  • the liquid can, further, be introduced instead through a slit or wall mounted on the tubular wall, or even through one or more inlet nozzles situated in the central part of the chamber at the supply end; the part of the liquid that strikes the tubular wall is carried along the wall as a film and is entrained by the gas by means of the projections.
  • the effect of the projections is to create local turbulence and to cause liquid on the tubular chamber wall both that which is' swept along the wall from the point of supply as well as that which is deposited thereon by droplets striking the wallto be entrained in the gas stream as small droplets. Thereby the presence of small droplets throughout the mass transfer section of the contacting is assured and mass transfer is improved.
  • FIGURE 1 is an elevation view of a multi-stage countercurrent contactor comprising a series of superposed units which are constructed according to the invention
  • FIGURE 2 is a vertical cross sectional view through one of the contacting units
  • FIGURES 3 and 4 are sectional views taken, respectively, on the lines 33 and 44 of FIGURE 2;
  • FIGURE 5 is an isometric view of a part of a unit, showing a modified liquid supply arrangement
  • FIGURE 6 corresponds to FIGURE 3 and shows a modification.
  • FIGURE 1 there are shown three identical contacting units 10, 11 and 12, supported on a gas inlet column 13 to which the gas is admitted via a duct 14.
  • the gas ascends through the several units and is, after repeated contact with liquid, discharged via a duct 15.
  • the liquid to be contacted is fed to the bottom or sup ply end of the contacting unit 12 through a supply conduit 16 and an annular distribution chamber 17, carried upward through the unit 12 in contact with the gas, and separated from the gas in a separator 18. It is transferred by a conduit 19 to the supply end of the next unit 11.
  • each contacting unit 12 comprises a tubular wall 25, here represented as a circular cylinder, which defines a contacting chamber and has open lower and upper supply and discharge ends.
  • the lower end has a plurality of liquid supply holes 26 spaced at equal circumferential intervals and communicating with the chamber 17 which surrounds the wall and to which the liquid is supplied.
  • a plurality of liquid supply holes 26 spaced at equal circumferential intervals and communicating with the chamber 17 which surrounds the wall and to which the liquid is supplied.
  • a vane deck 29 consisting of a plurality of sector-shaped vanes inclined to impart a rotational movement to ascending gas. This deck is preferably located somewhat below the top of the wall to provide a separating section.
  • the separator 18 includes an upper annular wall 30 mounted above the wall 25 and having a collar or stubpipe 31 extending downwardly at the inner edge thereof and situated coaxially with the tubular wall 25.
  • the collar 31 encloses a space the cross sectional area of which is similar in shape to but smaller than the cross sectional area of the chamber in the wall 25. Hence, when one is polygonal, both should be.
  • each unit except the lowermost rests on the plate 30 of the next lower unit and is supplied with a stream of gas which ascends through the collar 31 of such lower unit.
  • the separator further provides a sump, having a floor 32, for the collection of liquid.
  • liquid admitted from the distribution chamber 17 through the holes 26 directly to the wall 25 is carried along that wall by the gas stream, which ascends from any source, such as the next lower unit.
  • this liquid encounters the projections 27, 28, and liquid droplets are formed by gas entrainment. Droplet formation occurs throughout the said section, and any liquid which coalesces on the projections or the wall 25 is re-entrained in the gas.
  • This sweeping and dispersal action depends upon the gas velocity. It was found that, for example, when working with hydrocarbons having a vapor density of 4 kg. per cu. meter, that a gas velocity of 3 meters per second is sufficiently high to produce the above-described action.
  • the length of the said mass-transfer section may vary within wide limits, for instance, from 0.5 to 5.0 times the smallest diameter of the contacting chamber.
  • the gas flows through the vane deck 29 and is given a rotary motion about the central axis of the contacting chamber.
  • This sets up centrifugal forces whereby the dispersed liquid droplets are flung outwardly to the wall 25, while being swept upward by the gas.
  • the gas largely denuded of liquid, escapes through the collar 31 while the liquid moves outwardly over the rim of the tubular wall 25. Some of this liquid strikes the walls 30 and 18 and falls onto the fioor 32.
  • the wall 25 should extend above the vane deck for some distance, for instance, from 0.5 to 1.0 times the smallest diameter of the contacting chamber, although greater heights are feasible.
  • the inside diameter of the collar is chosen to be smaller, the quantity of liquid carried off by the gas becomes smaller, but the flow resistance in the gas stream increases.
  • the proper choice will, therefore, depend upon the desired operating characteristics of the unit, as determined by the desired conditions under which the contact between liquid and gas is to take place, such as gas velocity, rate of liquid supply and the desired extent of mass transfer.
  • the vane deck is provided for only one purpose, namely to spin the gas to set up centrifugal separating forces, the said deck can be designed for optimum performance of the separating function, using known expedients.
  • the vanes can be given the contours and inclinations best suited for flinging the liquid outwards. It may, however, be noted that some mass transfer will occur within the vane deck and in the section above the deck.
  • FIGURE 5 shows a modified construction wherein the liquid is supplied from the liquid supply conduit 16a to an annular trough which includes an annular floor 33 and a vertical wall 34 and is mounted at the supply end of the tubular wall 25. Liquid overflows the rim of the wall 34 and is first swept upwards and then entrained in the gas at the projections 27, 28, as previously described.
  • FIGURE 6 which is a cross sectional view corresponding to FIGURE 3, shows a modified shape of the tubular wall a, which is polygonal in the mass-transfer section below the vane deck.
  • the area in this section is, further, larger than that in the section above the vane deck, for which FIGURE 4 is applicable.
  • a column was formed with four contacting units, each having a cylindrical wall, placed coaxially in series as shown in FIGURE 1.
  • the diameter of each cylinder was 18 cm.
  • Supply of liquid took place via a circumferential slit of 1.5 cm. width, formed in the lateral wall.
  • the vertical distance between corresponding parts of adjacent units was 31 cm.
  • the grid consisted of squares with sides of 3.7 cm., the height of each strip perpendicular to the cylinder wall being 1.5 cm.
  • Above each grid of strips there was a vane deck with flat blades, with a blade angle of to the horizontal.
  • the portion of the cylinder beyond the vane deck was 8 cm. long; the diameter of the collar for checking the liquid was 15 cm., the collar protruded from the annular wall by a distance of 1 cm., and the distance between the underside of the collar and the opposite
  • the arrangement was a vertical one; the liquid flowed back to the preceding contacting apparatus by gravity.
  • the flow parameter is defined as q is the quantitative liquid flow, Q is the quantitative vapor flow,
  • Apparatus for contacting liquid and gas by concurrent flow which comprises:
  • gas inlet means situated centrally with respect to said axis for admitting a stream of gas to one end of said chamber for flow through said passage
  • liquid supply means for supplying liquid into said gas stream within the chamber directly from a point outside said wall at a level near said one end of the chamber for entrainment by said gas stream
  • Apparatus as defined in claim 1 wherein the said means for supplying liquid includes an annular trough mounted within the chamber in said wall, and means for supplying liquid to said trough.
